| titleOfInvention | Method for manufacturing an isocyanate-terminated prepolymer, prepolymer obtained thereby, and polyurethane resin |
| abstract | Provided is a method for manufacturing an isocyanate-terminated prepolymer. Said method includes: (a) a step in which an initiator is used to ring-opening polymerize a cyclic compound that contains an alkylene oxide, in the presence of a composite metal cyanide complex catalyst in an amount such that the metal content derived from said catalyst in a final polyol is between 1 ppm and 30 ppm by mass, thereby yielding a polyol composition containing the aforementioned catalyst; (b) a step in which water is added in an amount corresponding to 0.05-20% by mass of the polyol composition, without removing the composite metal cyanide complex catalyst from the polyol composition obtained in step (a), and the polyol composition is heat-treated in a sealed system; (c) a step in which the water-containing polyol composition from after step (b) is dehydrated until the water content therein reaches 5-500 ppm by mass; and (d) a step in which a polyisocyanate compound is added to the polyol composition from after step (c) and reacted with the polyol in said polyol composition. |
